Attention! After removing the cardan shaft, it is forbidden to start the engine and move the car.
Replacing the front propeller shaft must be carried out in the following order. Remove stiffening plate. Loosen the bolt nuts (arrows, fig. 10.35 am) fixing the elastic coupling, keeping the bolt heads from rotating. Move the cardan shaft to the rear and remove the flexible coupling with centering flange.
Disconnect the cardan shaft from the PK by moving it forward (pic. 10.36).
Check and, if necessary, replace the sealing ring of the centering element (arrow, fig. 10.37). Clean the connection slots and check their technical condition. Lightly lubricate the spline with a type of grease «Weicon Antisize».
Check centering element (1, fig. 10.38) and, if necessary, replace it. Lubricate the centering element with a paste of the type «Molykote Longterm 2PLUS» or «Optimol Olistamoly 2». Check and, if necessary, replace the O-ring.
Install the flexible coupling in such a way that the arrows on the coupling (pic. 10.39) were directed to the cheeks of the flange.
Replace self-locking nuts of M10 bolts (10.9) propshaft mounts. Tighten bolt nuts to torque:
- from the side of the front axle gearbox - 60 Nm (6.0 kgf·m);
- from the side of the transfer box shaft - 64 Nm (6.4 kgf·m).
